lo all whom it may concern.'

Be it known that t, @1111111.11 11. Gewinn. :1 citizen of the `United States, resii'line at Chicago, in the county oli tloohV and State ot' lllinois` have invented certain new and useful lniprovement's in Uil-(hips ot which the following; Yis a specification.

The Vpresent-invention relates to :111 oil cup such as is used with n1eehanisu1sI eenerN ally for containing` a luhricant to he Yted to certain oit the 11'1oval1le parts.

One object o't the present invention is to provide a loeliine mechanism carried hy the cup7 which will perinit nioveinent ot the ditl'ercnt sections coinprisingg; the cup toward one another, hut will prevent n'1ovenient of said sections away 'tfron1 one another to disasselnhle the parts.

Another object: ot the 'invention is to pro-- vide means for rendering' thialoeliiugniechanisn'i ine'tl'ective it it heconies necessary.

A 'further object is to provide ineans tor automatically moving); the looking nlelnher out o'tf actingposition atteithe parts have heen n'iovcd toward one another a` prede termined distance. And :1 `tui-ther ohject is to so arrange this lockingnieehanisni that it will not decrease the. capacity o't the cup or interfere in any way with the passage of the lubricant out iti-e111 the cup.

The invention turther consists in the. :teatures oit construction and conihination oit parts hereinafter deacrihed and claimed.

ln the drawings, Figure l is an elevation showingthe niovahle 111e111her o't the cup in section, with the partsI in the position they assume when .initially assembled; File'. 2, a view similar to Fig. '1, showing the inovahle n1en1hcr advanced to the point where the locking 111echani-in1 has heen retracted t'roni operative position; Fig. f5, a plan View OII the upper face of the tixcd seetion; and lfigg. t, an under 'tace view of the niovahle ineinher, showing theloclting111e111 her in its retraeted or non-operative posi tion.

.lin the use ot oil cups it has heen 't'ound that the cap or 111oval le portion which cone prises the reservoir t'or the lul1ricant will oftentimes hccoine loosened and separated :troni the fixed portion o1a the cup. This, ot course, destroys all et the utility ot. the cup and necessitates the frequent replenisliing;l of this portion ot the device.

It is the primary object of the present inl vention to secure the c1111 to the lived portion in :1 n1anner wherehy n1oven1e11t ol" the cap tendin 5 to disasstunhle it 'troni sueh tixed position is eheelied; and hence the cap is locked to the fixed portion in :1 nlanner to prevent ite hecoining.;v loosened and separated tl1ere't`ro111.

For the purpose ot illustratioin the de Avice is shown e111plo},'ed with :1n oil cup eonsistine ol! :1 tixed portion 5 and :1 n1ovahle portion tl. The tixed portion consists ot a steni i' adapted to he positioned upon the n1aehine :t the point where the luhricant is to he t'ed onto the operative parts. 't`he .stein terminatesI in a head S. which, as lehown inore. elearly in Fig. il, has its upper t'ace E) provided with a series ot.g teeth 10. which` as shown, are in the lorin ot" ratchet teeth; and the head Ew :1nd the .steln T have a here running` therethrough` which is the channel through which tho luhrieant passes onto the portions ot' the inaehine to he luhrieated. 'l`he niovahle section is in the 'torin ot :1 cap l2 havingl a screw-threaded interior 23, which ineahes with the screwthraided exterior l=l of the head S, and the interior oit the cap 12 :ietsl as a reservoir itor the luhrieant.

Il vingr upon the interior ot the cap l2 and resting` against the upper inner wall ot said cap is :111 arni l5, which is tixedly secured to :1 lserew-thr-eaded stein lt project'- ingr outside ol the cap,` and upon which stein is mounted :1 linurled thunlh-serew l?. rt`he arn1 tti terminates in a head 1S, in which is secured one end ot' :1` helieallvr coiled resilient locking' n1en1l1er 1.5); and the head is lturthcr provided with a tapered lug); Q0, which 1`1rovides a spaee Qt hetween the :11111 and tace ot said lue', which l'orlns a pocket to receive the acting' end ot the lockinel nieznher and maintain it out ot operative position, as will he more elearly hereinat'ter explained.

rl`he 'free end ot the helically coiled resilient n1en1l1er ttl is hentto vtorln a linger which is adapted to travel upon the toothed sur'laee ot the head S; and befause ot' the, .resilient nature ot the coiled n1en1l1er thisl finger will he constantly maintained in enejaejenient with the teeth ot the head S. And the .lodgingl ot this linger 2Q into the recesses produced by the formation of the teeth serres to lock the cap l2 against rota tive niovoincnt ahout the head 8 in a direction tending to separate the members from one another.

In practice the device is used as follows: The fixed portion 5 is secured in position on the machine; the cap 12 is filled with lubricant and mounted thereon. After the cap has been advanced a predetermined distance upon the head 8, the finger 22 of the locking member will engage with the teeth 10 upon the outer face of the head 8; and since these teeth are in the form of a ratchet tooth, they will permit of the movement of the cap to further advance it upon the head 8, because during this movement the fingered end 22 will merely ride over the face of the teeth. But when a reverse movement is imparted to the cap, the fingered end will then strike the vertical wall of one of the ratchet teeth and a locking action will result, preventing any further movement of the cap in this direction, which is the direction tending to remove the cap from the head. By this means, after the cap has been initially positioned upon the head, a retraction therefrom is prevented by any jolt or jar or other force or strain tending to remove it from proper position upon the head. 1t may happen, however, that it is desirable to remove the cap before it has been advanced to its limit of movement upon the head. if this is desired, the knurled thumb-nut 17 is loosened. This permits the arm 15, together with the locking member 19, to remain fixed while the cap is being revolved, in place of the arm being carried with the cap during its revolution, as it would be under norm al conditions. A revolution of the cap under these conditions, to remove the cap from the head, is possible, since the locking action caused by the striking of the finger against the face of the teeth is eliminated, so far as it tends to check the movement of the cap, the locking member remaining in fixed position and the cap revolving about it until it has been removed.

`When the cap has been advanced upon the head to its limit of movement, the free end of the wire will be forced underneath the lug 18 and into the pocket 21, and when in this position the free end is locked against movement and pressure of the finger against the face of the teeth eliminated. It is un derestood that when the end of the locking member is forced into the pocket, the movement causing this forcing is produced by the highest surface of the tooth; and since after such insertion the locking member 'willnot be free to move and follow along the face of the teeth and enter the depressed port-ions of the teeth, where the locking action occurs, the locking member will be thrown out of operative position with respect to the teeth and the cap will then be free to be revolved about the head and removed therefrom. Means are thus provided so that when the cap has been far enough advanced to force all the lubricant from the interior of the cap, the locking member will be automatically drawn out of operative position and retraction .of the cap from the head permitted, so that the supply of lubricant can be replenished.

1t is desirable in some instances to give a certain movement to the cap at regular intervals, in order to feed a certain amount of lubricant upon the parts of the machine to be lubricated. in the present instance the distance which the cap is moved can be accurately determined by the click or jar produced by the passing of the finger 22 over,

the toothed surface of the head 8; and by determining just what amount of lubricant will be fed4 by the movement of the cap this distance, an accurate feeding of the lubricant can be easily accomplished.

As will be seen from a study of the drawings, the locking member will lie close to the side of the cap, thus not decreasing to any appreciable extent the capacity of the cap nor interfering in any way with the feed of the lubricant,
